Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment method is used, then user can control light transmittance, but control is inflexible and requires vehicle unlocking
Solution Approach 1:
The switchable glass system automatically adjusts light transmittance based on detected distance information without requiring manual user input. The system serves itself by using sensors to detect proximity and automatically controlling the glass state, eliminating the need for user intervention and enabling control before vehicle unlocking.
Solution Approach 2:
The patent replaces manual mechanical button pressing with an automatic sensing and control system. Distance sensors detect the target object's proximity and trigger electrical signals to adjust the switchable glass, substituting the mechanical operation with an automated electromechanical system that provides flexible control.
2Adaptability or versatility
If automatic distance-based control is implemented, then control flexibility is improved, but device complexity increases
Solution Approach 1:
The control system integrates multiple functions into a single automated module that handles distance detection, signal processing, and glass control. This multi-functional approach achieves dynamic adaptability while consolidating components to manage system complexity.
Solution Approach 2:
The system adjusts the light transmittance parameter of the switchable glass based on changing distance parameters detected by sensors. By monitoring and responding to parameter changes in the environment (distance), the system achieves adaptability through automated parameter adjustment rather than complex control logic.

AI summary
A method and apparatus for controlling switchable glass and a vehicle and an electronic device. The method for controlling switchable glass comprises: acquiring distance information between a target object and a vehicle (S101); controlling an input signal of switchable glass of the vehicle according to the distance information (S 102); and changing the light transmittance of the switchable glass by means of the input signal (S103). Distance information between a target object and a vehicle is acquired, and an input signal of switchable glass is controlled according to the distance information, so that flexible regulation of the light transmittance of the switchable glass is realized, thereby improving the user experience.
